ARK-1220L - Intel Atom E3940 1.6GHz Embedded PC with dual 4K HDMI, dual Gigabit Ethernet, 4x USB3.0, and wide 12 to 28V DC power

Wide Temperature

These products utilise high quality industrial grade components enabling them to work in wide temperature environments. They are capable of running as low as -20C and as high as +70C.

Wide Voltage

These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.


M.2, formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. M.2 replaces the mSATA standard, which uses the PCI Express Mini Card physical card layout and connectors. Employing a more flexible physical specification, the M.2 allows different module widths and lengths, and, paired with the availability of more advanced interfacing features, makes the M.2 more suitable than mSATA in general for solid-state storage applications

Wireless Connectivity

These devices have built in wireless interface controllers enabling them to connect to a wireless network.


4G is the fourth generation of broadband cellular network technology, succeeding 3G, and preceding 5G. A 4G system must provide capabilities defined by ITU in IMT Advanced.

Windows 10

This system can be supplied with Windows 10 configured to your specification, including disk partitioning, driver and software installations, along with Windows feature setup and application-specific configuration.


These products use heatsink, heatpipe and extrusion technology to dissipate the heat generated by the system rather than using traditional fans thus improving system reliability and longevity.


WISE-PaaS (Platform as a Service) stands between the domain-specific cloud and IoT devices, providing a modular operating environment for system integrators. Not only does it provide seamless sensor information transmission and remote management control, its open RESTful API/SDK protocols establish standard connection and communication between all the sub-systems. The integrated IoT software and cloud platform plays a key role in the development of IoT applications, analysis of IoT big data, the continued optimization of work flow and future expandability of the system.


This system features USB3 ports for fast communication to peripheral devices.

MiniPCI Express

This system features one or more miniPCI Express (mPCIe) slots for board level expansion.

DIN-rail mountable

These devices have been designed to be mounted directly on to an industry standard DIN-rail.


Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys.


CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.

FCC Approved

The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.


This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.


Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.
